Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

open access: yesPest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus

open access: yesPest Management Science, EarlyView.
Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Impact of Two High‐Fiber Dietary Transitions on Fecal Consistency and Microbiota Composition in Captive Dromedary Camels (Camelus dromedarius) With Chronic Recurrent Diarrhea: A Pilot Study

open access: yesZoo Biology, EarlyView.
High‐fiber dietary interventions reshaped the gut microbiota of captive dromedaries with chronic recurrent diarrhea, but responses varied among individuals. Despite taxonomic shifts, microbial metabolic functions remained remarkably stable, supporting the resilience of the dromedary gut ecosystem and the use of fiber‐based dietary management.

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...
